- Ensure 99.9% air purity to prevent costly paint shop and surface contamination.
Compressed Air Products for Automotive Industries
Pneumatic systems are used in conjunction in automotive production areas, including assembly, welding, painting, fabrication and test areas. The compressed air system must also be stable, free from moisture, flow instability and contamination during the shift, or the production quality will be compromised.
Frank Compressors manufactures rotary screw compressors, VFD screw compressors, PM motor compressors, oil free compressors, refrigerated air dryers and air receiver tanks designed specifically for automotive manufacturing.
